AI Article Synopsis
- The study focused on creating a quick and reliable UPLC-MS method for detecting acetochlor in biological samples.
- It involved using specific ion transitions for quantification and effective separation techniques with optimized mobile phases.
- The method was validated with excellent linearity, accuracy, and precision, and was successfully applied in a pharmacokinetics study of acetochlor in MCF-7 cells.
Article Abstract
The aim of this work was to develop a fast, simple, and reliable UPLC-MS method for the sensitive detection of acetochlor in biological samples. In MS mode, the ion transition m/z 270.1 → 224.1→148.1 was chosen for quantification with butachlor as the internal standard. In the UPLC system, separation was performed on a UPLC column (2.1 × 50 mm ID, 1.7 μm) with 0.1 % FA in water and acetonitrile as mobile phases. After simple protein precipitation via acetonitrile, the method was well validated with good linearity (0.5-20 ng/mL, r > 0.995), accuracy (-3.70 %-2.98 %), and precision (<15 %). The selectivity and sensitivity were improved obviously in MS mode than that in MRM mode. The developed UPLC-MS method was successfully applied to the cellular pharmacokinetics study of acetochlor in MCF-7 cells.
